Both units have a good population of elk. IMO your plan of going the first week is spot on. My experience in the areas is that other than opening weekend you will have little to no pressure in many areas. Finding bulls still on summer patterns, or even batched up is not uncommon, they may be in the open somewhat patternable. They will still be pretty lazy, but any weather switches will create some activity in my experience. And some bulls will be starting to get the itch.
The last ten day although generally no shortage of bugles or elk sign, finding unpressured elk is very tough. My expereince was Somewhat easier in Pine creek. The wilderness has some nooks and crannies that they hole up in. Dont worry so much about going deep in the trail sense as this will often lead to outfitted areas with pressure. Be prepared to switch up tactics a bit and if you do get a good response get in very tight before attempting to setup as any hint of foul play is likely to send him runnning.
I have personally had best success eastside during the first week, killing a couple bulls in consecutive years partners and I opening week. Small 6 points after passing some bulls opening weekend. Depending on the year I actually prefer to spend the last week on the westside.
